问题

I get the error in the subject of this post when I use the CLI to create a new component: ng g c my-component --project=my-project (No component is created)

I've seen other posts with the same error message, but none of them also include Nrwl/Nx, which I believe is somehow involved. Project started as Ng4 and was upgraded to Ng6.

Any ideas how I can fix this?

Thx.

UPDATE #1

I tried dropping the --project flag entirely ( so just ng g c my-component) and still get the same problem. Not sure what that means, yet.

Quick fix

1) Change current directory in cmd/terminal to src/app

cd src/app (linux)

cd .\src\app\ (windows)

2) Run commands now

ng g c myComponent

回答2:

The generate of components aims to do 2 things:

create source code for the component
registers the component in a module (by default, in the app.module.ts)

The problem is, that you don't have an app.module.ts. You renamed it to something else, or perhaps even have multiple of them. In that case there are 2 possible solutions:

you do the registration of the component manually. (easiest)

ng g component mycomponent --skip-import
you specify the module with the -m switch. (might be broken) There is a long thread about it here: https://github.com/nrwl/nx/issues/526

I ended up totally deleting node_modules, clearing out the yarn cache and then running yarn to reinstall all packages. I also edited my angular.json file so that my pathing looked like this for all applications and libraries:

"root": "libs/my-lib",
"sourceRoot": "libs/my-lib/src"

I'm not sure which of those fixed the problem, but all appears to be OK now. At least the immediate problem went away.

Hopefully this helps someone else.

I had the same issue, In angular.json file, I searched for my-project-e2e (replace my-project with your project name) and then I changed:

"root": "" to "root": "e2e" and saved it. Everything was working again.

The solution was specified in this link.

First way:
I think first you have to go to inside your app folder then type cmd;
ng g c your_com_name --spec false
or ng g c your_com_name
It will definitely create your component or solve your problem.

second way:
Remove your e2e from your angular.json->projects:
definitely

{ 
    your_project_name-e2e:{}
}

example: my-first-app-e2e

{
      "root": "e2e/",
      "projectType": "application",
      "architect": {
        "e2e": {
          "builder": "@angular-devkit/build-angular:protractor",
          "options": {
            "protractorConfig": "e2e/protractor.conf.js",
            "devServerTarget": "my-first-app:serve"
          }
        },
        "lint": {
          "builder": "@angular-devkit/build-angular:tslint",
          "options": {
            "tsConfig": "e2e/tsconfig.e2e.json",
            "exclude": [
              "**/node_modules/**"
            ]
          }
        }
      }
    }

回答6:

Had same issue. Turned out to be somehow related to the name of the root component. Renaming back to 'app' resolved the problem

回答7:

I removed the line "cli": { "defaultCollection": "@nativescript/schematics" } from angular.json file and it worked for me.

回答8:

This also happened to me and in my case it was due to me generating a new component outside of the app folder, I bought the new component inside the app folder and the issue was solved.

回答9:

Run component generation command(ng g c component-name) from where the app.module.ts file is located.
